,METALLIC FRAMEWORK FOR BUHIDINGS- Application filed October 28, 1927. Serial No. 229,017.

This invention relates to building construction employing in its frame-work upright and horizontal steel members of standard cross-sectional formation, and Hi improvements consist in the selection 0 steel members having appropriate cross-section, interfitting said members, and providing suitable uniting means, also in fabricating walls from said members prior to their erection.

It is the purpose of my invention to utilize steel I beams, channel beams and angle beams, with suitable connecting means, in

producing building frame-work, and in the interest of economy to employ these beams in certain given lengths so that they may be used interchangeably in wall construction, irrespective of the style or size of the building to be constructed.

Other features and advantages of my invention will hereinafter appear.

In the drawings:

Figure 1 is a floor plan of a building showing the arrangement of beams in interfitting, connective relation according to my invention.

Fig. 2 is an enlarged partial view of Fig. 1.

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 2.

Fig. 4 is a vertical section taken on the line H of both Figs. 2 and 3.

Fig. 5 is a detail, in vertical sectionshowing a modified form'of connecting means, and

Fig. 6 is a section on the line 6-6 of Fig. 5.

In the production of steel frame-Work for a building according to my invention I employ vertical I beams 1 of a length equal to the height between floors. The I beams are spaced apart suitably throughout the Width of the wall of which they form the frame uprights, the flanges of the Ibeams respectivelylying in planes parallel to the outer and inner wall surfaces, and their webs lying transversely through said walls.

In the framework of walls that meet to form corners of a building oneof the terminal beams is of channel section, bearing the reference numeral 2, the web of this beam lying against a flange of a terminal I beam of the adjacent Wall, to which it is connected. The means of connection employed consists of a plate 3 secured by a bolt 4 to the-web of channel beam 2, said bolt clamping the plate 3 upon a flange of the adjacent I beam.

I beams disposed as horizontal members to serve as flooring supports are indicated at 5, said I beams 5 being interposed bet-Ween the opposed upper and lower ends of vertical I beams 1 for succeeding stories. As means for reinforcing the fabricated frame structure of vertical and horizontal I beams I place horizontally disposed angle beams 6 transversely across the I beams 5, against the upper and lower surfaces thereof, respective flanges of the angle beams 6 lying against the flanges of I beams 1 and intermediate the ends of said I beams 1 and the flanges of I beams 5. Then in order to connect the I beams 1, angle beams 6, and I beams 5 -I place plates 7 against the horizontally disposed flanges of angle beams 6 and connect said plates to the flanges of I beams 5 by bolts 8, thereby clamping the horizontal flanges of angle beams 6 between the plates 7 and the flanges of I beams 5. It will be understood that the vertical flanges of angle beams 6 are secured as by bolting, riveting or welding to the flangesof I beams 1.

At 9 I have indicated wire lath for interior wall surfacing, and at 10 wire lath to carry stucco or other exterior finish.

In Figs. 5 and 6 I have illustrated modified means of uniting associated vertical and horizontal component elements of my improved fabricated frame structure at their points of intersection, these'modified means requiring the emfployment of only a single bolt and a pair 0 plates in place of the four bolts and two pairs of plates shown in Figs. 1 to 4.

Thus, in said Figs. 5 and 6 will be seen the same horizontal I beam 5, vertical I beams 1 and horizontal angle beams 6 as appear in Figs. 1 to 4, the uniting means in the modification however comprising a pair of I shaped flat plates 9 disposed at opposite sides of the horizontal I beam 5, transversely thereof, with their respective flanges engaged with the horizontal members of the angle beams 6 above and below I beams l. A. single bolt 10 connects the plates 9, said bolt passing through a hole provided there for in the web of I beam '5. As is apparent in Fig. 6 the act of screwing up the nut on bolt 10 has the effect of drawing the plates 9 toward each other and bowing them, to thereby create a tensional grip that serves to prevent loosening of the nut and thus proyides a permanent connection.

Variations within the spirit and scope of my invention are .equally comprehended in the foregoing disclosure.

I claim:

1. Fabricated metallic frame-work for buildings comprising vertical I beams in endwise opposed relation, horizontal angle beams engaging respectively the upper and lower ends of opposed vertical Ibeams, horizontal I beams disposed transversely intermediate opposed anglebeams in alignment with opposed vertical I beams, and means for connecting a group composed of vertical I beams, horizontal angle beams and a horizontal I beam at the intersection of said group. 7

2. Fabricated metallic frame-work for buildings comprising a vertical I beam, a vertically disposed channel beam whose web lies against a flange of said horizontal I beam, and means for connecting said web and flange. I

3. Connecting means for a group of metallic structural elements comprising a horizontal I beam, angle beams transversely disposed respectively above and below said I beams, and opposed vertical I beams engaging said angle beams in alignment with said horizontal I beam, said connecting means consisting of plates lying across the angle beams, respectively at each side of the webs of the Vertical I beams, and bolts securing said plates to the flanges of said horizontal I beam.

4. Connecting means for metallic structural elements comprising a'vertical I beam and a vertical channel beam whose web lies for a portion of its length against a flange of said beam, said connecting means conslstlng of a plate opposed to said I beam flange and said channel web and a bolt se; 4

curing said plate to said Web.

5. Connecting means for a group of metallic structural elements comprising a horizontal I beam, angle beams transversely disposed respectively above and below said I beam, and opposed vertical I beams engaging said angle beams in alignment with said horizontal I beam, "said connecting means consisting-of I shaped plates placed respectively at opposite sides ofsaid horizontal I beam, the flanges of said plate engaging respectively with the angle beams above and below said horizontal I beam, and a bolt tensionally connecting said plates through the web of said horizontal I beam.

6. Conne;;ting means for a group of metallic structural elements comprising a horizontal I beam, parallel angle beams transversely disposed respectively above and below said I beam, and opposed vertical I beams engaging said angle beams in alignment with said horizontal I beam, said connecting means consisting of I shaped plates placed respectively at opposite sides of sail horizontal I beam, the inner-edges of theflanges of said plate engaging respectively with the horizontal legs of said angle beams above and below said horizontal I beam and a bolt connecting said plates and adapted to flex the same into tensional gripping relation with said I beam.
